An established multiscale model for materials is used as the basis for a failure model for fiber composites. The model’s computation is explained so that its results can be used to formulate the inputs to the failure model. ...

Nonlinear estimators based on the Kalman filter, the extended Kalman filter (EKF) and unscented Kalman filter (UKF) are commonly used in practical application. The Kalman filter is an optimal estimator for linear systems; ...

A new design procedure was developed and documented that uses commercial-off-the-shelf software (MATLAB, SolidWorks, and ANSYS-CFX) for the geometric rendering and analysis of a transonic axial compressor rotor with splitter ...

The outboard bearings that support shafts in naval ships and submarines present unique challenges to designers, shipbuilders, and operators. Such bearing must operate continuously and reliably in demanding environments ...

The use of lattice Boltzmann methods (LBM) for fluid flow and its coupling with finite element method (FEM) structural models for fluid-structure interaction (FSI) is investigated. A body of high performance LBM software ...

This study examines various computational techniques to analyze dynamic response and failure of sandwich composite materials subject to fluid-structure interaction characterized by an acoustic field or the propagation of ...

The uniformity (homogeneity) of nondeforming particle distributions in a cast alloys microstructure is highly important in controlling the materials strength, ductility, and fatigue resistance. Friction stir processing ...

This work introduces a new information-centric pseudospectral optimal control based algorithm for autonomous trajectory planning and control of unmanned ground vehicles with real-time information updates. It begins with ...
